Before you buy a 240 you should try and drift the prelude. Find an open parking lot that is not around anybody and try and spin it out. Then you can start doing little drifts but make sure you have a lot of run off for whipping back and understeering. See if you like it first.
It is fun but you dont need a 240sx to have fun.
Also come to the drift days. We have lots of fun (even though I dont drive).
